Spiral steel pipes are made by steel coil, extrusion forming under the normal temperature, then taken the technology of double wire and double-faced submerged-arc welded.
During molding process of spiral welded steel pipe, steel plate has uniform deformation and light residual stress, thus the surface has no scratches. Spiral Steel Pipe has more flexible thicknesses and diameters, especially in making high-grade thick pipes with small or medium aperture, these techniques has incomparable advantages in satisfying your needs.
Application:
Spiral steel pipe is mainly used in public waterworks, petrochemical industry, chemical industry, electric power industry, agricultural irrigation and urban construction etc.
For liquid transportation: water supply, drain water, petroleum transportation, etc.
For gas transmission: coal gas, steam, liquefied petroleum gas, gas etc.
For structure: piling, bridge, wharf, road, architectural structure, etc.
